Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and more specifically, to a limiting device and a printing press thereof. Background Technology

[0002] Digital printing presses directly output graphic information onto the substrate using digital technology. Employing digital control, they can quickly meet personalized, small-batch printing needs, offering rich color reproduction and high precision. Suitable for printing on various materials such as paper and biodegradable food containers, they provide a flexible and efficient solution for the printing industry. Their working principle involves using digital signals to control the print head, precisely spraying ink onto the paper substrate. Color printing can be completed without plate making, and the printing content can be quickly adjusted according to requirements, achieving personalized customization while ensuring vibrant colors and clear patterns. In the paper printing field, they possess advantages of high efficiency, flexibility, and precision, meeting the needs of small-batch, multi-variety printing. Since the material position during the printing process directly affects the subsequent printing effect, printing limit operations are necessary.

[0003] In related technologies, during the use of printing presses, limiting rods are generally installed on both sides of the top of the printing press conveyor belt to limit the material being transported during the printing process.

[0004] However, in the current use of printing presses, since the limit rod can only restrict the movement of materials, in actual use, the staff needs to place the material to be printed on the inside of the limit rod so that the printing press conveyor belt can transport and print the material. This makes the material limiting and feeding operation inconvenient and labor-intensive, affecting the flexibility and processing efficiency of the printing press's material limiting operation.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4This utility model provides a technical solution: a limiting device and its printing machine, including a fixed frame 1 and a material limiting mechanism. A fixed rod 2 is fixedly connected to the top of the inner side of the fixed frame 1, and a fixed pad 3 is fixedly connected to the bottom of the inner side of the fixed frame 1. It can limit the external printing material while pre-storing the material for printing, so that the user can stack and release the same batch of materials at the same time as limiting the printing material. This avoids the situation where the printing machine needs to repeatedly limit and place the material, which is inconvenient for the material limiting and loading operation and requires a lot of labor for the staff. Therefore, it improves the flexibility of the material limiting operation and the processing efficiency of the printing machine.

[0021] Reference Figures 1-4 In a preferred embodiment, the material limiting mechanism includes a limiting plate 4, which is movably connected to both sides of the left side of the fixed rod 2. A limiting strip 5 is fixedly connected to the bottom right side of the limiting plate 4. A baffle 6 is movably connected to the left side of the fixed rod 2. A horizontal plate 7 is fixedly connected to the top right side of the baffle 6. A limiting translation mechanism is fixedly connected to the right side of the limiting plate 4. By using the fixing frame 1 in conjunction with the fixing pad 3 and the fixed rod 2, the limiting plate 4 and the baffle 6 are installed at the feeding end of the external printing machine. Then, according to the actual limiting requirements of the printing material, the limiting plate 4 is moved horizontally by hand to adjust the lateral limiting range of the limiting plate 4. Then, the horizontal plate 7 is moved upward to move the baffle 6 to adjust the longitudinal limiting height of the baffle 6. This allows the limiting plate to move horizontally. 4. Together with the limiting strip 5 and the baffle 6, it provides a medium for pre-storing and limiting the printed material during use. The limiting translation mechanism includes a translation ring 8, a screw hole 9, and a bolt 10. The translation ring 8 is fixedly connected to the right side of the limiting plate 4 and is sleeved on the outside of the fixing rod 2. The screw hole 9 is opened on the top of the translation ring 8, and the bolt 10 is threaded into the inside of the screw hole 9. It can perform translation adjustment, connection guidance, and tight fixing work between the limiting plate 4 and the fixing rod 2, so that the user can translate and adjust the limiting space inside the limiting plate 4 according to the actual size of the external material, and perform tight fixing operation between the adjusted limiting plate 4 and the fixing rod 2. Therefore, it improves the convenience of translation adjustment and fixing between the limiting plate 4 and the fixing rod 2.

[0022] Reference Figures 2-3In a preferred embodiment, fixing holes 11 are provided on the inner sides of both the fixing frame 1 and the fixing pad 3. A fixing plate 12 is movably connected inside the fixing holes 11, which can be used to secure the fixing frame 1 to the external printing machine. This facilitates the installation and fixing of the fixing frame 1 to the printing machine by the user, avoiding difficulties in installation. Therefore, the installation and fixing of the fixing frame 1 is improved. A screw cylinder 13 communicating with the fixing holes 11 is fixedly connected to the outer side of the fixing frame 1. A stud 14 fixedly connected to the fixing plate 12 is threaded inside the screw cylinder 13. This can prevent separation between the fixing plate 12 and the fixing frame 1 and provide a medium for the user to apply a clamping force to the fixing plate 12. This avoids difficulties in applying force to secure the fixing frame 1 to the external printing machine by the fixing plate 12, thus improving the clamping and fixing force application effect of the fixing plate 12.

[0023] Reference Figures 2-4 In a preferred embodiment, a screw groove 15 is provided at the top of the horizontal plate 7. A screw rod 16, extending to the bottom of the horizontal plate 7, is threadedly connected inside the screw groove 15. The bottom of the screw rod 16 is connected to the top of the fixing rod 2. The horizontal plate 7 can be used to thread a connection between the baffle 6 and the fixing rod 2, and provide a medium for the user to adjust the working height of the baffle 6 and the horizontal plate 7. This avoids the situation where the horizontal plate 7 and the baffle 6 are difficult to adjust during use, thus improving the ease of adjustment of the horizontal plate 7 and the baffle 6. Connecting sleeves 17 are fixedly connected to both sides of the top of the fixing rod 2. Connecting seats 18 are movably connected inside the connecting sleeves 17. The top of the connecting seats 18 is fixedly connected to the bottom of the screw rod 16, which can rotate the connection between the screw rod 16 and the fixing rod 2 to prevent separation and displacement. This avoids the situation where the screw rod 16 separates from the fixing rod 2 or shifts in position when used with the horizontal plate 7 and the baffle 6, thus improving the connection effect between the screw rod 16 and the fixing rod 2.

[0024] Reference Figures 2-4 In a preferred embodiment, by embedding and fixing a magnetic sheet 19 at the top of the fixed rod 2 and embedding and fixing a magnetic suction sheet 20 at the bottom of the connecting seat 18, which is magnetically connected to the magnetic sheet 19, the connecting seat 18 can magnetically fix the screw 16 and the fixed rod 2 after operation, thus avoiding the screw 16 from rotating easily during use and causing the working position of the horizontal plate 7 and the baffle 6 to change, thereby improving the working stability of the screw 16.

[0025] A printing press, suitable for the aforementioned limiting device. Specifically, the working process or principle of this limiting device and its printing machine is as follows: During use, the handheld fixing frame 1 is moved to the outside of the external printing machine's loading end. At this time, the fixing rod 2, in conjunction with the translation ring 8, drives the limiting plate 4 to the top of the external printing machine's conveyor belt. Simultaneously, the screw 16, in conjunction with the screw hole 9, through the connecting sleeve 17 and the connecting seat 18, drives the horizontal plate 7 and the baffle 6 to follow the fixing rod 2 to the top of the external conveyor belt, preparing for subsequent limiting of the printed material. During this process, the protrusion on the bottom inner side of the fixing frame 1 and the fixing pad 3 should contact the surface of the external printing machine, so that the fixing frame 1 can effectively limit the movement of the fixing rod 2 and the printing machine. Initial installation and support work is performed. Then, the stud 14 is held and rotated in conjunction with the screw cylinder 13 to apply a threaded thrust to the fixed plate 12, causing the inner side of the fixed plate 12 to contact and abut against the surface of the printing machine. This secures the fixed frame 1 to the printing machine. Subsequently, based on the printing limit width and height requirements of the external printing materials, the limit plate 4 is moved horizontally to adjust the limit width on the inner side of the limit plate 4. At this time, the translation ring 8 moves with the limit plate 4 outside the fixed rod 2, performing translational connection guidance and anti-deviation separation work between the limit plate 4 and the fixed rod 2. After the limit plate 4 is adjusted, the bolt 10 is rotated. The bolt 10 is moved downwards through the screw hole 9 to contact and tighten with the surface of the fixing rod 2. This causes the bolt 10, in conjunction with the translation ring 8, to fix the adjusted fixing rod 2 and the limiting plate 4. Then, the screw 16 is rotated to engage the screw groove 15, applying an upward threaded adjustment force to the horizontal plate 7 and the baffle 6. This changes the discharge height between the bottom of the baffle 6 and the external printing machine conveyor belt. At this time, the connecting seat 18 rotates with the screw 16 inside the connecting sleeve 17, establishing a rotatable connection between the screw 16 and the fixing rod 2. The magnetic plate 19, in conjunction with the magnetic suction plate 20, magnetically positions the screw 16 and the fixing rod 2 after the operation. Then, the material to be printed and limited is stacked and placed inside the limiting plate 4. At this time, the limiting plate 4 limits the material laterally, and the baffle 6 limits the material longitudinally. When the printing machine conveyor belt is working, the bottom layer of the stacked material moves with the conveyor belt and moves out of the stacked material inside the limiting plate 4 through the discharge space between the bottom of the baffle 6 and the conveyor belt. At this time, the limiting strip 5 works with the limiting plate 4 to continue to transport and limit the material that has moved out. At the same time, the stacked material inside the limiting plate 4 moves downward and contacts the printing machine belt due to its own gravity. This cycle is used to pre-store, transport and limit the printing material.
